Resumo: Objectives: to identify common clinical characteristics in patients with superior semicircular canal dehiscence (SSCD)in order to increase the diagnostic suspicion of this recently described clinical entity. Materials and Methods: a retrospective analysis was carried out between 2016 and 2019 and 5 cases were analyzed, corresponding to 8 ears with SSCD, analyzing the accompanying symptoms. The diagnosis of dehiscence was established through computed tomography (CT) of the temporal bone. Results: Hearing loss was the major complaint being common to all patients. In the 8 ears analyzed, there was a predominance of conduction hearing loss in frequencies below 1000Hz with normal impedance audiometry. Conclusions: the recognition of these patients, with a third non-physiological window in the bony lining of the superior semicircular canal, makes possible a differential diagnosis that explains a conduction or mixed hearing loss with acoustic reflexes present, thus preventing errors in diagnosis and unnecessary surgery.

Material e Métodos: realizou-se uma análise retrospetiva entre 2016 e 2019 e analisaram-se 5 casos, correspondendo a 8 ouvidos com DCSS, analisando a sintomatologia acompanhante. O diagnóstico de deiscência foi estabelecido através da tomografia computorizada do osso temporal. Resultados: a hipoacusia foi o motivo de referenciação comum a todos os doentes. Nos 8 ouvidos analisados coexistiu predominantemente, uma hipoacusia de condução nas frequências inferiores a 1000Hz com impedanciometria normal. Conclusões: o reconhecimento destes doentes, com uma terceira janela não fisiológica no revestimento ósseo do canal semicircular superior, concretiza uma possibilidade de diagnóstico que explica uma hipoacusia de condução ou mista com reflexos estapédicos presentes, prevenindo, desta forma, erros de diagnóstico e cirurgias desnecessárias.Sociedade Portuguesa de Otorrinolaringologia e Cirurgia de Cabeça e Pescoço2021-09-04info:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/articleapplication/pdfhttps://doi.org/10.34631/sporl.820https://doi.org/10.34631/sporl.820Portuguese Journal of Otorhinolaryngology and Head and Neck Surgery; Vol. 59 No. 3 (2021): September; 267-271Revista Portuguesa de Otorrinolaringologia e Cirurgia de Cabeça e Pescoço; Vol. 59 Núm. 3 (2021): Setembro; 267-271Revista Portuguesa de Otorrinolaringologia-Cirurgia de Cabeça e Pescoço; Vol. 59 N.º 3 (2021): Setembro; 267-2712184-6499reponame:Repositórios Científicos de Acesso Aberto de Portugal (RCAAP)instname:FCCN, serviços digitais da FCT – Fundação para a Ciência e a Tecnologiainstacron:RCAAPporhttps://journalsporl.com/index.php/sporl/article/view/2889https://journalsporl.com/index.php/sporl/article/view/2889/911Direitos de Autor (c) 2021 Revista Portuguesa de Otorrinolaringologia e Cirurgia de Cabeça e Pescoçoinfo:eu-repo/semantics/openAccessCarção, AndréCosta, Joana BorgesAbreu Pereira, DiogoDuarte, DelfimNeves, MartaAzevedo, Paula2024-06-06T13:00:41Zoai:journalsporl.com:article/2889Portal AgregadorONGhttps://www.rcaap.pt/oai/openaireinfo@rcaap.ptopendoar:https://opendoar.ac.uk/repository/71602025-05-28T17:54:30.281301Repositórios Científicos de Acesso Aberto de Portugal (RCAAP) - FCCN, serviços digitais da FCT – Fundação para a Ciência e a Tecnologiafalse
